objective c - What are faulted entities in Core Data?

问题描述:

What are faulted entities and what the difference between them and 'usual' entities? where can I read about that?

Thanks

网友答案:

ADC has some documentation on this topic:

Faulting reduces the amount of memory your application consumes. A fault is a placeholder object that represents a managed object that has not yet been fully realized, or a collection object that represents a relationship:

All objects are loaded on demand to reduce memory usage. override -(void) awakeFromFetch/Insert and -(void) willTurnIntoFault to do custom initialization
